Anthropogenic influences on fish behaviour

The link between fish physiology and behavior is vulnerable to disturbance through human impacts. Chemical pollution, thermal pollution, human noise, habitat destruction and the release of non-native species are some examples of how we have altered the environments in which fishes live. Many types of anthropogenic disturbance target specific physiological systems; disruption of sensory systems, brain function, respiration and reproduction can all affect fish behavior. This article considers the main ways in which human activities are known to affect the fragile link that exists between behavior and physiology, focusing particularly on the effects of chemical contaminants.
